Discovered in their intimate dance, the siblings freeze, hearts pounding. The girl, her eyes wide with fear and desire, backs away, leaving her brother bereft. But the dance isn't over. She returns, pushing him onto the closet floor, mounting him reverse-cowgirl style. She rides him hard, her moans stifled, as he grips her hips, thrusting up into her. Their bodies slap together, the scent of sex heavy in the confined space. As they climax together, they collapse, spent and breathless, their taboo dance complete.
